International Society of Automation released a new standard in the ISA-62443 series addressing risks stemming from the use of business information technology cybersecurity solutions. The use of such solutions is growing in complex and dangerous manufacturing and processing applications to mitigate vulnerabilities in industrial automation and control systems (IACS), but security goals often differ for IACS and IT. While IACS prioritizes control system availability, plant protection and operations, and time-critical system response, IT security focuses on protecting information rather than physical assets.
